Designed to thwart anyone with the audacity to put you on hold, the Telecom Audio Voice Over is a device that allows you to listen to anything you want to whenever you're on hold. Operation is simple: plug the base of your telephone into one of the phone jacks, and your headset into the other. Then, you plug your favorite compatible media player into the stereo or mono 3.5mm jack.
Now, you can play music or podcasts over your phone's headset whenever you're on hold—or even when you're not: if you want, you can keep the music blasting, and the person on the other end of the line will never hear it.
Once you connect the Voice Over, you never have to remove it. Just plug in your media whenever you need to. The Voice Tap works with any telephone that has a detachable handset cord, including single- or multi-line phones, digital or analog phones, and phones equipped for VoIP. For many telephones, it will allow you to keep listening over the headset even when you're not taking or receiving a phone call.
